Judge Avery's daughter Viola (Ester Ralston) is arrested in a police raid on
Chinatown's most notorious gambling casino. Facing public disgrace and her
father's anger, Viola romances immigration officer Bob Baxter (Regis Toomey) who
provides an alibi for her. Baxter is drawn to Viola but also sees her as a
source of information about the casino boss's white slavery ring.
As Baxter's attention becomes clouded with infatuation, Viola must keep the
inquisitive detective at bay. Owning a debt of silence to the casino's owner,
King Moss (Sidney Blackmer), Viola finds herself ensnared in a dark web of
Western intrigue and Oriental crime. Growing feelings for Baxter drive Viola
into danger and she is kidnapped as a pawn in Moss's elaborate underworld
scheme.
